（07）使用WireMock快速伪造REST服务

Posted 2020-12-06 javasl

　　WireMock功能强大，本文记录一下它一个基础功能，快速伪造REST服务。

　　1、下载WireMock独立运行包

　　进入官网http://wiremock.org，点击Docs，Running as a Standalone，点击downloaded the standalone JAR下载

　　

　　

　　2、运行jar包，启动WireMock服务

　　进入包所在文件夹，指定端口，运行一下命令：

java -jar wiremock-standalone-2.26.3.jar --port 9062

　　

　　3、演示效果

　　1）添加依赖 

<dependency>
    <groupId>com.github.tomakehurst</groupId>
    <artifactId>wiremock</artifactId>
    <version>2.5.1</version>
    <type>pom</type>
    <scope>test</scope>
</dependency>

　　2）测试方法

public class MockServer {

    public static void main(String[] args) {
        WireMock.configureFor(9062);
        WireMock.removeAllMappings();
        WireMock.stubFor(WireMock.get(WireMock.urlPathEqualTo("/order/1"))
                                 .willReturn(WireMock.aResponse().withBody("{"id":1}").withStatus(200)));
    }
}

　　运行main方法，浏览器输入：http://localhost:9062/order/1，显示：{"id":1}，访问成功。

　　现在是在类中写返回的json串，下面改为在txt文件中设置返回的json串。

public class MockServer {

    public static void main(String[] args) throws IOException {
        WireMock.configureFor(9062);
        WireMock.removeAllMappings();
        mock("/order/1","01");
        mock("/order/2","02");
    }
    
    private static void mock(String url,String file) throws IOException {
        ClassPathResource source = new ClassPathResource("com/edu/sl/wiremock/response/"+file+".txt");
        List<String> list = FileUtils.readLines(source.getFile(),"UTF-8");
        String content = StringUtils.join(list,"
".charAt(0));
        WireMock.stubFor(WireMock.get(WireMock.urlPathEqualTo(url))
                                 .willReturn(WireMock.aResponse().withBody(content).withStatus(200)));
    }
}

　　在com/edu/sl/wiremock/response目录下，新建01.txt、02.txt

{
    "id":1,
    "type":"A"
}

{
    "id":2,
    "type":"AC"
}

　　重新运行一下main函数，将结果刷到WireMock服务器中，在浏览器访问：

　　http://localhost:9062/order/1，页面显示01.txt的内容

　　http://localhost:9062/order/2，页面显示02.txt的内容
